A new version of the four player co-op Call of Duty: ZOMBIES game has hit the iPhone and iPod Touch in Call of Duty: World at War: ZOMBIES II. Yes that title is a mouthful.
The new version of the game is purchasable for $9.99 and contains one map - the Shi No Numa level. If you own the original ZOMBIES game, you can purchase the map for $4.99. Both games are compatible with each other so you shouldn't have a problem finding other co-op gamers in either local blue-tooth or online co-op. Shi No Numa adds in new weapons, new traps and of course - the dreaded hell hounds.
